The properties of fractal apertures fed by rectangular waveguide has been investigated in this chapter. The self similarity and space filling properties of fractal geometries are exploited to achieve multiband radiation. Some self-affine fractal geometries suitable for waveguide fed apertures, have been proposed and investigated. It is shown that the scale factor of the fractal geometries can be used as a design parameter for controlling the resonant frequencies. The problem has been solved using method of moments (MoM) and the numerical results are verified through simulation on HFSS.
